Study Population

Patients diagnosed with Adolescent Idiopathic Diagnosis

You may qualify if:

  • Diagnosis of Adolescent Idiopathic Scoliosis
  • Failed external brace therapy defined as either (a) progression of the curve greater than 5 degrees at any time while undergoing external brace therapy, or (b) inability or unwillingness to comply with at least 16 hours per day of external bracing
  • Skeletally immature (Risser Sign 0, 1, 2, or 3)
  • In girls, either (a) pre-menarchal, or (b) post-menarchal by no more than 6 months
  • Age between 10 and 15
  • Primary Cobb angle greater than 25 degrees but not yet requiring spine fusion
  • Candidate for surgical implantation of spinal instrumentation
  • Patient resides locally with respect to the Investigator's clinic and is willing and able to comply with the requirements of the protocol
  • Must sign informed consent to permit the use of personal health data

You may not qualify if:

  • Patients with a pacemaker, implanted cardiac defibrillator, or any other electronic implant
  • Patients who require an MRI following implantation
  • Skeletally mature (Risser Sign 4 or 5; or fused tri-radiate cartilage)
  • Diagnosis of other musculoskeletal or developmental illness that might be responsible for the spinal curvature
  • History of previous surgical treatment for AIS
